The Dead Sea has received much attention in the past few years due to the fact that it is the lowest body of water on earth, and that body of water is drying up. Melanie Lidman, writer for The Times of Israel, prepared a series of three articles about the Dead Sea drying up last month here, here, and here.
Today Lidman writes about a study done by Columbia University’s Lamont-Doherty Earth Observatory and published in the past few days. For a period of 40 days and nights in 2010 scientists drilled 1500 feet into the floor of the Dead Sea. What they found was fascinating. Let Lidman tell the story:
Scientists who drilled 450 meters (1,500 feet) into the floor of the Dead Sea announced this week that the region may have been affected by “epic” centuries-long droughts, much worse than researchers previously believed.
The study, led by Columbia University’s Lamont-Doherty Earth Observatory and scientists from six countries, examined a geological sample revealing more than 200,000 years of climate history in the Dead Sea region.
The scientists studied the thickness of the salt layers, as well as liquid bubbles trapped in the layers of salt, to determine precipitation and runoff to the Dead Sea, uncovering some alarming trends.
According to the study, the region experienced two major drought periods when rainfall and runoff patterns were at some points less than 20% of the average rainfall for the 20th century.
You must go to the article here to see the photograph of a sample of the geological core from the Dead Sea. A report with the same photograph made be found on the page of the Lamont-Doherty Earth Observatory here.
Last year we called attention here to a fabulous article by Nir Hasson in Haaretz.
